Label inspection device and method

An apparatus is provided having a tag check circuit responsive to a target address to: identify a guard tag stored in a memory system in association with a block of one or more memory locations, the block including a target memory location identified by the target address; performing a tag check based on the guard tag and an address tag associated with the target address; and in response to detecting a mismatch in the tag check, performing an error response action. The apparatus also has tag mapping storage circuitry for storing mapping information indicative of a mapping between the guard tag value and the corresponding address tag value. The tag check circuit remaps at least one of the guard tag and the address tag based on the mapping information stored by the tag mapping storage circuit to generate a remapped tag for use in the tag check. 本发明提供了一种装置，该装置具有标签检查电路，该标签检查电路响应于目标地址以：识别防护标签，该防护标签与一个或多个存储器位置的块相关联地被存储在存储器系统中，该块包含由该目标地址识别的目标存储器位置；基于该防护标签和与该目标地址相关联的地址标签来执行标签检查；以及响应于在该标签检查中检测到失配，执行错误响应动作。该装置还具有标签映射存储
